Flexible container with pouring spout

Claim 1

A strip of containers for fluids connected integrally in series, each container including a pair of coextensive opposed walls of flexible material constituting a body portion and a tapered spout for dispensing fluids and each container of the series having peripheral margins along which the walls are fixed to each other, said margins including first and second parallel rectilinear side margins at least approximately equal in length extending along the strip, a third margin along the bottom of the container, and a fourth margin along the top of the container, said third margin being curved outward in relation to the middle of said body portion when the container is flat and said fourth margin being curved inward toward the middle of said body portion of the container, portions of said first and fourth margins of each container converging toward respective ends to define said tapered spout, said first and second side margins of each container being substantially offset in relation to each other so that the upper end of the first side margin at the tip of the spout projects substantially upward beyond the upper end of the second side margin, each said container being adapted to be flat when the container is empty, the third and fourth margins of each container being curved at least approximately alike and crossing said strip, respective third and fourth margins of successive containers being adjacent one another and unitary at least along part of the lengths thereof so as to interconnect the containers of the strip, thereby producing containers having a relatively high ratio of container volume to wall surface without significant waste of material.
